Samsung S90D / S94D 48" (WRGB OLED) vs Samsung Q7F

In the tested movie scenes, the Samsung OLED 48 S90D television achieves impressive brightness results, exceeding 800 nits in the first four shots, which can be considered a very good outcome. In the case of the last shot, where a full-screen burst of sunlight is visible, the brightness drops to around 400 nits but still remains at an acceptable level. However, it is worth noting that this model in larger sizes offers higher values, exceeding the "barrier" of 1000 nits. Additionally, speaking of the DCI-P3 colour space coverage value of 97% is an excellent result, which guarantees extremely rich and realistic colour reproduction, further enhancing the picture quality. However, once again it should be remembered that the panel in the 65' variant equipped with a QD-OLED panel will be even better in this aspect. For those hesitating about the size of the S90D model, it is worth noting that larger versions of this television offer a better HDR effect, and consequently, a higher score in our tests.

Unfortunately, the Samsung Q7F is not one of the bright televisions, which directly impacts the quality of HDR films. The peak brightness of the panel is only around 250 nits, which is definitely insufficient for claiming a true cinematic experience. In practice, the HDR content does not differ significantly from classic SDR, making it difficult to talk about any "wow effect" that usually accompanies us when watching such films. During testing of film scenes, the image simply looked dark, and the brightness almost always hovered around the aforementioned 250 nits. The worst performance came from shots with small, intensely glowing elements – the global dimming technique used reacted very aggressively in those cases, dimming the entire screen to maintain the black effect. However, it is worth noting the presence of a QLED coating that broadens the colour spectrum. For a budget QLED model, the Q7F performs quite decently here: the DCI-P3 colour gamut coverage is around 93%, and BT.2020 reaches 70%. This means that despite the low brightness, the colours can still look quite vivid and attractive.

The S90D Samsung TV has been tested in Filmmaker mode, which offers good colour reproduction, although with some imperfections that may be noticeable to more demanding users. This mode may seem a bit too warm, and users who switched from Standard mode may experience a slight shock. It's worth considering that this state of affairs is caused by poor settings, such as white balance, rather than the Filmmaker mode itself. Both in SDR and HDR content, the device exhibits drops in blue, causing colours to appear warmer than they should. In practice, this means that some shades, like sky blue or skin tones, may seem less natural and take on a pinkish or yellowish tint. The Colour Checker test confirms these deviations, showing shifts towards warmer tones. In SDR content, the gamma chart indicates minor fluctuations, resulting in a slightly darker image, especially in the shadows. This may affect the clarity of details in darker scenes. Conversely, in 4K HDR materials, the EOTF curve is above the recommended line, leading to some portions of the image being too bright, which can cause clipping in the brightest areas. Overall, the Samsung S90D presents a solid image straight out of the box, but for the best results, particularly with more demanding content, additional calibration is recommended.

The reproduction of factory colours in the Samsung Q7F is definitely not one of its strong points. In Filmmaker mode, which theoretically should be closest to neutral, the white balance issue is immediately noticeable. There’s too much red on the screen, while blue is lacking. The effects are very easy to notice – white, instead of being neutral, takes on warm, almost slightly orange tones. In the long run, this makes the entire image appear a bit unnatural, while bright areas of the scene can seem unrealistic. The problems are even more evident in HDR content. The charts show that the TV has significant errors in the Color Checker palette, which results in visible inaccuracies in the real image. In practice, this means that colours are not presented as they should be. The Q7F also heavily manipulates brightness; darker elements are overly boosted, causing them to lose their cinematic feel, while bright parts can be dimmed. This makes the image seem flattened, and contrast, instead of helping to bring out details, only highlights its own limitations. In HDR materials, this is particularly frustrating because every detail matters. In scenes where a subtle play of light and shadow should be felt, the Q7F either overdoes the lighting or, conversely, suppresses elements that should attract the eye. This causes the image to lose its depth, and instead of cinematic realism, we have a rather simplified effect.

After calibration, the Samsung OLED 48 S90D in movie mode looks even better than one might have assumed. The white balance, for both HD and 4K HDR content, has been improved to near perfection. Although minor errors can still be noticed, they are so minimal that they do not significantly affect the picture quality. Colours are more balanced, which translates into a natural reproduction of details, especially in scenes requiring a precise colour palette. It’s worth noting that this model in the 48' size is equipped with a WOLED panel that has different characteristics compared to larger sizes and has a smaller coverage of a wide colour gamut, not offering as rich colours as, for example, the 65-inch version, which is equipped with a QD-OLED panel.

Contrast has also seen significant improvement. The gamma chart after calibration is much closer to the expected line, providing better balance between the bright and dark portions of the image. The EOTF curve, which showed issues with overexposed scenes before calibration, now shows better results. This effect allows for greater detail retention in bright parts of the image, particularly in HDR material.

After professional calibration, we managed to bring the Q7F to order – at least in terms of SDR content. The image in this mode looks really good: the white balance has been set correctly, the colours appear natural, and the errors in the colour palette have dropped to levels practically invisible to the eye. Gamma behaves exemplary, and the only minor flaw remains a slight lightening of smaller elements, which stems from the lack of local dimming. For everyday watching of television or films in standard quality, the Q7F performs surprisingly well.

It was significantly more challenging to tame HDR content. Despite adjusting the white balance, the television still heavily manipulates brightness, causing scenes to appear unnatural – what was meant to be subtly darker can sometimes be overly bright, and the bright parts of the image can occasionally be dimmed. The final effect is better than in factory settings, but it’s clear that the construction limitations of the Q7F do not allow for fully utilising the potential of HDR materials.

The Samsung OLED 48 S90D television performs exceptionally well in smoothing tonal transitions. Thanks to the technology used, the transitions between colours are more fluid and natural. It is also possible to utilise the noise reduction feature, which further smooths tonal transitions, which can be useful in some situations. However, it's worth remembering that turning on noise reduction can also lead to the smoothing of desired film grain, which may reduce the cinematic feel of the picture. For this reason, caution is advised when using this feature, as it's better to leave the natural grain that adds character and authenticity to the content being viewed.

Samsung, as always, does not disappoint, and in terms of scaling images from lower resolutions, it performs excellently. The S90D OLED 48 Samsung television effectively processes lower resolutions, as seen in the visible photo. The outline of the model is clear and correct, making it look natural and detailed. Furthermore, the branches of the trees are well reproduced, showing no significant jaggedness that could detract from the image quality. Thanks to effective scaling, even lower resolution materials look attractive on the screen, satisfying users who prefer diverse content sources such as regular antenna/cable television.

Upscaling and digital image processing in the Q7F is a bit of a rollercoaster. On one hand, we have really nice upscaling – weaker sources look better than you might expect. The image becomes clearer, sharper, and even older films or free-to-air TV hold up well. Samsung has been strong in this area for years, and the Q7F confirms that. On the other hand… things start to get tricky. The TV has a problem with overscan – part of the image is simply cut off, and it doesn't look very elegant. Additionally, we were let down by a feature called "noise reduction," which should improve the smoothness of tonal transitions in weaker materials. In other Samsungs, it works relatively well, but here it practically makes no difference – the banding in gradients is still there. It's a bit of a shame because we expected more from a model that is aimed at users looking for a display for SDR content.

The S90D television is equipped with a 120 Hz panel, with the ability to "overclock" to 144 Hz with the right PC configuration, providing exceptional motion smoothness. Samsung has been offering a variety of image clarity settings on a ten-point scale for years, allowing users to customise the display to their preferences. In the UFO test, thanks to the use of an OLED panel, there's no question of any ghosting. The response time of the pixels is instantaneous and perfectly captures dynamic movements. In this aspect, OLED technology is considered one of the best on the market. The picture is extremely sharp and detailed, even during fast action, making the S90D OLED 48 Samsung television the perfect choice for gamers and sports enthusiasts.

Motion blur and motion fluidity in the Q7F is probably the most budget-friendly aspect of this television. The 60 Hz panel makes the motion blur quite noticeable, especially in dynamic scenes, and it's rather hard to consider this model as equipment designed for watching sports or playing fast-paced games. In tests with the little green man, there was a long trail, similarly, the ball in a football match would leave behind streaks.

On the positive side, the presence of motion smoothing is worth noting. In films, it really makes a difference – especially since most materials are recorded in 24 frames. Here we can decide whether we prefer a more "cinematic" image, with a slight judder typically found in cinema, or a smoother, more “TV-like” one. This actually works quite well and helps improve the viewing comfort for series or movies.

The Samsung OLED 48 S90D television is well-suited to the needs of gamers, offering four HDMI 2.1 ports that support features such as Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and HGIG (HDR Gaming Interest Group). With these technologies, gamers can enjoy smoother gameplay and faster on-screen response, significantly enhancing comfort during long gaming sessions. Additionally, the Game Bar feature allows for easy adjustment of settings, such as aspect ratios, which can be particularly useful in different types of games. For PC users, the television offers an impressive refresh rate of 144Hz, and Nvidia and AMD graphics cards support G-Sync and FreeSync, further improving image smoothness. Although the lack of Dolby Vision support may be a drawback, it's worth noting that in gaming, this technology is not as widely used as in films. Nevertheless, the S90D still offers excellent features for gamers, making it a great choice for those seeking high-quality visuals and advanced gaming technologies.

The features for gamers on the Samsung Q7F is a topic that stirs up quite a few mixed emotions. On one hand – no reasonable person was expecting miracles here, after all, it’s a 60 Hz television and it was clear from the get-go that this wouldn’t be equipment to squeeze the maximum from a console or PC. On the other hand, since the manufacturer promised specific solutions in promotional materials, it is only natural that we wanted to see them in practice. At the start, it’s looking pretty good. The automatic game mode (ALLM) works, so there’s no need to manually fiddle with the settings; the console switches the TV to low latency mode by itself. Plus, we have the Game Bar, which looks impressive and allows you to check a few basic parameters without leaving the game. And this is where the good news ends.

The biggest problem with the Q7F is VRR, or rather its absence. Indeed, the appropriate icon appears in the menu, you can even see it in the Game Bar, but throughout the entire test, the function remained dead and could not be activated in any way. Even more disappointing is the matter of HGiG; this option was actually available in the beginning, but after a software update, it disappeared completely, which is just unprofessional. Therefore, the Q7F is only suitable for absolute basics. Sure, you can turn on the console, play calmer titles, and enjoy low input lag, but if someone is counting on more advanced features that the manufacturer promised, they will be disappointed. This is not a television one buys with gaming in mind, and it’s better to be aware of this before purchasing.
